Okay, so I just built this new PC ( My first build. ) And I've been running the PC for like 1 and a half hour, but it seems that my CPU ( Vishera 6300 ) goes down to 1.5GHz or somewhere below 2.0 sometimes and my entire system becomes "Unresponsive", even the internet dies down. I say unresponsive with quotes because it still works, I can drag stuff around and tab around, just that google freezes up and the internet shuts itself down for a minute or 2.

EDIT : Restarted, still happens. I also noticed that everything becomes unresponsive for about a minute before resuming normally. I can drag things around, minimize them and stuff, but I can't do anything inside them or open any other program... if I do try to open something, nothing will happen until after a minute when everything I did suddenly works. Same thing with doing stuff inside the programs, it won't process in real time, but after a minute or so, everything that I tried to do suddenly works on them.

I'm not exactly sure what causes it or whatever, but aside from that, everything runs smoothly. When it doesn't do that, it runs like a charm.
